Passivity-preserving parameterized model order reduction using singular values and matrix interpolation Vrije Universiteit Brussel Universiteit Gent
We present a parameterized model order reduction method based on singular values and matrix interpolation. First, a fast technique using grammians is utilized to estimate the reduced order, and then common projection matrices are used to build parameterized reduced order models (ROMs). The design space is divided into cells, and a Krylov subspace is computed for each cell vertex model. The truncation of the singular values of the merged ...
Passivity-preserving interpolation-based parameterized model order reduction of PEEC models based on scattered grids Vrije Universiteit Brussel Universiteit Gent
The increasing operating frequencies and decreasing IC feature size call for 3-D electromagnetic (EM) methods, such as the Partial Element Equivalent Circuit (PEEC) method, as necessary tools for the analysis and design of high-speed systems. Very large systems of equations are often generated by 3-D EM methods and model order reduction (MOR) techniques are commonly used to reduce such a high model complexity. A typical design process ...
Physics-based passivity-preserving parameterized model order reduction for PEEC circuit analysis Vrije Universiteit Brussel Universiteit Gent
The decrease of integrated circuit feature size and the increase of operating frequencies require 3-D electromagnetic methods, such as the partial element equivalent circuit (PEEC) method, for the analysis and design of high-speed circuits. Very large systems of equations are often produced by 3-D electromagnetic methods, and model order reduction (MOR) methods have proven to be very effective in combating such high complexity. During the ...
Parameterized Model Order Reduction of Delayed PEEC Circuits Vrije Universiteit Brussel
In this paper, we propose a novel parameterized model order reduction technique for circuits described by the delayed partial element equivalent circuit method. The moment vectors associated with frequency are excluded while forming the moments' subspace. This leads to obtaining very compact parameterized reduced order models. An implicit multiparameter moment matching algorithm is used for the moments related to the design parameters. ...
